Abstract (en)
An object of the invention is to provide a switch that can prevent leakage of an SF6 gas and reduce the amount of SF6 gas to be used. To achieve the object described above, the invention is characterized in that an arc-extinguishing chamber including an insulating tube, a fixed end plate provided at one end of the insulating tube, a movable end plate provided at the other end of the insulating tube, a fixed electrode provided on the fixed end plate, a movable electrode that is allowed to move and so provided as to pass through the movable end plate, a bellows attached to the movable end plate and the movable electrode, and a supply/discharge port for supplying and discharging a gas, a first bushing conductor electrically connected to the fixed electrode, and a second bushing conductor electrically connected to the movable electrode are provided, and the arc-extinguishing chamber, the first bushing conductor, and the second bushing conductor are embedded in a molded solid insulator to form a switching section.
